     The present game system includes: a jackpot drawing apparatus; a decision information detecting unit for detecting decision information for deciding whether a player is present at each of a plurality of game apparatuses, and a player presence decision unit which, at a predetermined timing after a drawing unit of the jackpot drawing apparatus determines a game apparatus which has won the jackpot award, decides whether a player is present at a winning game apparatus based on a result detected by the decision information detecting unit; wherein a jackpot payout processing unit performs a jackpot payout process for the winning game apparatus where the player presence decision unit decides that the player is present at the winning game apparatus, but does not perform the jackpot payout process for the winning game apparatus where the player presence decision unit decides that the player is not present at the winning game apparatus.

TECHNICAL FIELD

The present invention relates to a game system provided with a jackpot drawing apparatus for selecting a game apparatus which wins a jackpot award among a plurality of game apparatuses and also to a jackpot drawing apparatus constituting the game system.

BACKGROUND ART

Conventionally, this type of jackpot drawing apparatus includes, for example, a drawing machine utilized in a game system constituted with a plurality of token-operated game machines (game apparatuses) installed at a game center and others (for example, refer to Patent Document 1). In general, a token-operated game machine controls game progress on the condition where a token (bet object) is received from a player and a predetermined number of tokens (payout objects) paid out to the player according to the game result thereof An explanation will be made for an example of the token-operated game machine in which a jackpot drawing apparatus is utilized. That is, the number of tokens (bet objects) corresponding to a part of the number of the tokens received from a player is added accumulatively and kept as payout amount data at a payout amount storage unit of the jackpot drawing apparatus. Then, when a predetermined drawing start condition is satisfied, a drawing is performed by the jackpot drawing apparatus to determine whether a jackpot award is won or the jackpot award is lost (loss). When the jackpot award is won in this drawing, the number of tokens corresponding to at least a part of the payout amount data is paid out to a player who has satisfied the predetermined drawing start condition and the payout amount data is returned to an initial value.

In general, a jackpot drawing apparatus is often utilized in a game system constituted with a plurality of game apparatuses, each of which is provided with a game progress control unit which carries out a game independently. This is due to the following reasons. That is, the number of tokens which is allowed to be paid out to a player at one time by an individual game apparatus is limited to some extent by the individual game apparatus. Therefore, where the jackpot drawing apparatus is utilized in a single game apparatus, the number of tokens paid out at the time of winning the jackpot award thereof is largely limited to its upper limit by a maximum payout amount set in the game apparatus concerned. In contrast, where the jackpot drawing apparatus is utilized in a game system made up of a plurality of game apparatuses, the number of tokens paid out at the time of winning the jackpot award thereof can be determined for its upper limit by a sum of maximum payout amounts in the plurality of game apparatuses. In this instance, as compared with a case where the jackpot drawing apparatus is utilized in a single game apparatus, it is possible to increase the number of tokens paid out at the time of winning the jackpot award. As a result, an expectation can be given to a player that a great number of tokens would be paid out at one time by winning the jackpot award, thereby attracting the interest of the player. Due to the above-described advantage, the jackpot drawing apparatus is more often utilized in a game system constituted with a plurality of game apparatuses than in a single game apparatus.

In particular, recently, there is known a game system constituted with game apparatuses installed in a plurality of gaming arcades (game facilities). The jackpot drawing apparatus can be utilized also in this type of game system.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

A conventional jackpot drawing is in general performed in a manner that a player who plays a game with each game apparatus satisfies a jackpot drawing start condition during the game play and thereby a determination is made for whether the game apparatus concerned wins a jackpot award. However, where the jackpot drawing start condition is a condition that is not related to a game play played by the player who plays with each game apparatus, a situation where a jackpot award is won in a game apparatus which is not played by the player can be developed. Thus, in a conventional jackpot drawing, the jackpot drawing start condition is required to be related to a game play played by the player in each game apparatus. Therefore, a problem arises that the jackpot drawing start condition is low in the degree of freedom.

Further, in a conventional game system, where a process that a single jackpot drawing is performed to determine a game apparatus which wins a jackpot award from a plurality of game apparatuses is performed, a situation where the jackpot award is won in a game apparatus which is not played by a player can be developed. Thus, the above-described process cannot be performed, thereby a problem arises which causes various disadvantages, for example, failure in carrying out a performance for determining the jackpot award from a plurality of game apparatuses.

In general, in a jackpot drawing, it is necessary to avoid a situation where after a winning player leaves a game apparatus, a jackpot is paid out to the player. In a conventional jackpot drawing, a player who plays a game with each apparatus usually satisfies a jackpot drawing start condition during the game play, thereby performing a process that a determination is made for whether a jackpot award is won by the game apparatus concerned. Then, when the player satisfies the jackpot drawing start condition during the game play, the jackpot drawing is immediately performed. And, a large-scale winning performance is carried out for the player immediately after winning of the jackpot award is determined Therefore, a case where before a winning player is aware of having won the jackpot award, the player leaves the game apparatus, hardly occurs. Thus, a situation hardly occurs that after the winning player leaves the game apparatus, a jackpot is paid out to the player.

However, a reason why the above situation hardly occurs in a conventional jackpot drawing is that various conditions have been set to an extent so as to prevent a situation where before a winning player is aware of having won a jackpot award, the player leaves a game apparatus. Therefore, in a game system of performing the conventional jackpot drawing, a problem of causing disadvantages, for example, deterioration in the degree of freedom in setting various conditions arises.

In an attempt to carry out a drawing performance (performance to the effect that a jackpot drawing is to be performed from now or the drawing is in progress) in a relatively long jackpot drawing, for example, in order to liven up the jackpot drawing, a case can be frequently found where before a winning player is aware of having won a jackpot award, the player leaves a game apparatus. Since a jackpot drawing is usually set to be extremely low in its winning probability, a player has a very small expectation of winning the award and when the player finishes playing with a game apparatus, the player often leaves the game apparatus even when the jackpot drawing is still in the middle of performance. Therefore, conventionally, a relatively long performance is not carried out which may develop a situation where before a winning player is aware of having won a jackpot award, the player leaves the game apparatus.

Further, for example, in a case where a jackpot drawing is started under a condition which is not related to a game play played by a player with each game apparatus, the player often leaves the game apparatus at a timing at which the player finishes playing with the game apparatus even when the jackpot drawing start condition is satisfied. In this case as well, a situation where before a winning player is aware of having won a jackpot award, the player leaves the game apparatus can be frequently found. Therefore, in a conventional jackpot drawing, a jackpot drawing start condition is made so as to be related to a game play played by a player with each game apparatus. For example, a player that bets tokens for playing a game is regard as a jackpot drawing start condition. Thereby, a situation has been avoided where a player who has satisfied a jackpot drawing start condition leaves a game apparatus at a point in time when the player has satisfied the condition or the player leaves the game apparatus immediately thereafter. Thus, conventionally, there is no jackpot drawing in which the jackpot drawing start condition is made so as not to be related to a game play played by a player with each game apparatus.

A game system which utilizes a jackpot drawing apparatus is applicable to pachinko machines and slot machines installed at a pachinko parlor and others, in addition to those installed at a game center and others. The above problem is also found even in this type of game system.

The present invention realizes and provides a game system capable of improving disadvantages such as a limited jackpot drawing performance and a lower degree of freedom in setting a jackpot drawing start condition and also a jackpot drawing apparatus which constitutes the game system.

Means for Solving the Problem

As an aspect of the present invention, it is listed that a game system including a plurality of game apparatuses, each of which comprises a game progress control unit for performing game progress control, comprises: a jackpot drawing apparatus, which performs a jackpot drawing in which at least one of the plurality of game apparatuses is regarded as a drawing target, including: a drawing unit for performing a jackpot drawing process to determine a game apparatus that wins a jackpot award among the plurality of game apparatuses, a payout amount storage unit which, when the drawing unit determines the game apparatus which has won the jackpot award, stores payout amount data indicating an amount containing an amount of payout objects to be paid out to a player who plays with the winning game apparatus, a jackpot payout processing unit which, when the drawing unit determines the game apparatus which has won the jackpot award, performs a jackpot payout process for reading out the payout amount data from the payout amount storage unit and paying out at least a part of the amount of payout objects corresponding to an amount indicated by the read-out payout amount data to the player who plays with the winning game apparatus, and a payout amount increasing unit for cumulatively increasing an amount indicated by the payout amount data stored in the payout amount storage unit when a predetermined payout amount increasing condition is satisfied; a decision information detecting unit for detecting decision information for deciding whether a player is present at each of the plurality of game apparatuses; and a player presence decision unit which, at a predetermined timing after the drawing unit determines the game apparatus which has won the jackpot award, decides whether the player is present at the winning game apparatus based on a result detected by the decision information detecting unit; wherein the jackpot payout processing unit of the jackpot drawing apparatus performs the jackpot payout process for the winning game apparatus where the player presence decision unit decides that the player is present at the winning game apparatus, but does not perform the jackpot payout process for the winning game apparatus where the player presence decision unit decides that the player is not present at the winning game apparatus.

In this game system, at a predetermined timing after winning of the jackpot award has been determined, confirmation is made for the presence of a player in the winning game apparatus. When the player is not present at the game apparatus, the jackpot payout process is not performed in the game apparatus. Thereby, it is possible to avoid a situation where the jackpot is paid out to a winning player who leaves the game apparatus before being aware of having won the jackpot award. Therefore, there is no case where various conditions such as a jackpot drawing performance and a jackpot drawing start condition are limited to an extent so as to prevent a situation where the winning player leaves the game apparatus before being aware of having won the jackpot award.

In the above-described game system, the jackpot drawing process may be to determine whether when a predetermined drawing start condition is satisfied by any one of the plurality of game apparatuses, the game apparatus which has satisfied the predetermined drawing start condition wins the jackpot award.

Where a game apparatus which wins a jackpot award is determined by a single drawing from a plurality of game apparatuses, it is often necessary to adjust a timing for performing a jackpot drawing individually among the plurality of game apparatuses. However, where the jackpot drawing can be performed individually in each game apparatus as described in the present game system, it is not necessary to adjust a timing for performing the jackpot drawing among a plurality of game apparatuses. It is, therefore, possible to simplify a jackpot drawing process.

In the above-described game system, the jackpot drawing apparatus may be provided with an alternative winning determination processing unit for performing an alternative winning determination process in which a game apparatus that wins the jackpot award is determined from two or more game apparatuses excluding the winning game apparatus among the plurality of game apparatuses, where the player presence decision unit decides that the player is not present at the winning game apparatus, and the jackpot payout processing unit of the jackpot drawing apparatus may perform the jackpot payout process for a player who plays with the game apparatus determined by the alternative winning determination processing unit where the player presence decision unit decides that the player is not present at the winning game apparatus.

A method for processing in a case where the player presence decision unit determines that a player is not present at the above winning game apparatus may include a method in which the player is not notified that winning of the jackpot award has been determined and a jackpot is not paid out. In this case, the same situation where a jackpot award has not been won in view of the player can be provided. However, there is a case where, for example, a performance is carried out that an advance notification that winning of the jackpot award has been determined is issued to players in a state of being unable to comprehend a winning player and a notification that who was the winning player is issued after a while. In this case, when a situation developed where the winning player leaves a game apparatus after issuing the advance notification, not winning the jackpot award would leave a largely unpleasant feeling in terms of game progress.

In the present game system, as a method for processing in a case where the player presence decision unit determines that a player is not present at the above winning game apparatus, a method in which the alternative winning determination processing unit is used to give the jackpot award to another game apparatus is adopted. Thereby, a game can be kept in progress without any unpleasant feeling even in a situation which would make it difficult to cancel the winning of the jackpot award.

In the above-described game system, at least one game apparatus among the plurality of game apparatuses may comprise a credit data storage unit for storing credit data, a bet-object receiving unit for receiving bet objects and a credit processing unit for performing a credit process to decrease by a value corresponding to an amount of bet objects received by the bet-object receiving unit, credit data stored in the credit data storage unit, and to increase the credit data by a value corresponding to an amount according to an amount of bet objects received by the bet-object receiving unit on the basis of the result of game progress controlled by the game progressing unit; the decision information detecting unit may detect, as the decision information, credit presence information indicating that the credit data is stored in the credit data storage unit in the above-described at least one game apparatus; and the player presence decision unit of the jackpot drawing apparatus may use a decision based on credit presence information on the winning game apparatus detected by the decision information detecting unit, that the credit data is stored in the credit data storage unit of the winning game apparatus, as a condition for deciding the player presence at the winning game apparatus.

In this game system, it is possible to accurately decide whether a player is present at a game apparatus which performs the credit process for increasing or decreasing credit data.

In this game system, it is possible to accurately decide whether a player is present at a game apparatus for controlling game progress depending on the individual information corresponding to the player identification information read out by the identification information reading-out unit.

In the above-described game system, at least one game apparatus among the plurality of game apparatuses may use, as the decision information detecting unit, a presence detecting unit for detecting whether a player is present at a predetermined playing position at which the player of the game apparatus is normally located, and the player presence decision unit of the jackpot drawing apparatus may use the player presence at the winning game apparatus which is detected by the presence detecting unit, as a condition for determining the player presence at the winning game apparatus.

Since the player presence is directly detected in this game system, it is possible to accurately decide whether a player plays with the game apparatus.

[Horse-Racing Game Machine 1000]

The token-operated game machine 1000 is a horse-racing game machine.

In the horse-racing game machine 1000, one or at least two players predict an order of arrival for a horse race played in the horse-racing game machine, and when the prediction is correct, the player is capable of receiving a token payout according to odds against that order.

FIG. 2 is an outline view showing one example of the horse-racing game machine 1000.

The horse-racing game machine 1000 is provided with a field unit 1002 arranged at the center portion and a plurality of stations 1010, as game apparatus, arranged to surround the field unit 1002. In the field unit 1002, a field surface 1004 as a moving surface that resembles turf on a race track on which a starting gate 1003 as a model is installed, is arranged, and when a plurality of model horses (not shown) are moved within the field surface 1004, a race is developed. Around the field unit 1002, a plurality of speakers 1005 for providing live race coverage, cheers, etc., are placed. Above the field unit 1002, placed are: a display unit 1006 for displaying, for example, a total accumulated token count indicating the number of pieces to be paid out for a total jackpot drawing described later; an illuminating device 1007 for illuminating the field unit 1002; and a camera 1009 that is an imaging unit functioning as imaging means for imaging the field unit 1002. The display unit 1006, the illuminating device 1007, and the camera 1009 are supported by a support column 1008. The speaker 1005 and the illuminating device 1007 that are performance units functioning as performance means of the horse-racing game machine 1000.

In the station 1010, a display 1011 for displaying thereon a game screen according to the progress of the game, and a touch panel 1012 overlapped on a display surface of the display 1011, are arranged. When a player touches a predetermined position of the game screen displayed on the display 1011 according to an instruction on the game screen, the position is detected by the touch panel 1012 and an operation content of the player is recognized by the horse-racing game machine 1000. In the station 1010, further arranged are: a token drop-in unit 1013 into which a token is dropped in by the player; a token payout opening 1014 from which the token is paid out to the player; and a magnetic-card inserting slot 1015 into which a magnetic card for recording thereon data that becomes necessary when the game is resumed is inserted.

In the horse-racing game machine 1000, races having the same titles as those of actual horse races held by the Japan Racing Association are sequentially held according to a predetermined cycle. For races held during one year, about 60 races are prepared, and for each race, a time for betting a token, i.e., a time for purchasing a betting ticket; a time during which a race is held by model horses; and a time for displaying race results are secured. The player predicts the order of arrival for each race, and is capable of freely purchasing a betting ticket. The purchasing of the betting ticket is performed by betting a token, and when the purchased betting ticket matches the results of the race, the player is paid out, as a dividend, tokens of which the number of pieces corresponds to that obtained in accordance with the number of pieces of tokens to be bet and odds.

In the horse-racing game machine 1000 in the present embodiment 1, the field unit 1002 forms the field surface 1004, and on the field surface 1004, an artificial lawn resembling an actual turf and models such as a starting gate 1003, etc., are arranged. A model horse as a moving body is moved on the field surface 1004.

FIG. 3 is a control block diagram showing a main control unit for controlling the whole operation of the horse-racing game machine 1000 in an integrated way.

FIG. 4 is a control block diagram showing a station control unit arranged in each station 1010.

As shown in FIG. 3, the main control unit 1100 placed on the field unit side is provided with: a main control device 1101; a movement control device 1102 for controlling a movement of the model horse in the field unit 1002; an illumination control device 1103 for controlling the illuminating device 1007; an audio control device 1104 for controlling the cheers, the live coverage, etc., provided by the speaker 1005; an SRAM 1105 and a flash memory 1106 for temporarily recording data processed by the main control device 1101; a ROM 1107 in which a program necessary for the game and various types of databases are stored; and an external communication device 1108 for performing data communication via a LAN with an external device such as the gaming arcade server 5000. The main control device 1101 is connected to each of the movement control device 1102, the illumination control device 1103, the audio control device 1104, the SRAM 1105, the flash memory 1106, the ROM 1107, the external communication device 1108, and the camera 1009. In the ROM 1107, a movement control program that is movement control information for each model horse, various types of data relating to each horse used for the race, a database for a race schedule, etc., are stored.

As shown in FIG. 4, the station control unit 1200 arranged in each station 1010 is provided with: a station control device 1201; a token managing device 1202 for managing a payout of the token and any other similar task; a RAM 1203 for temporarily recording various types of data of the player; a magnetic-information reader 1204, that is identification information reading-out unit functioning as identification information reading-out means, for reading magnetic information, such as an ID code etc., which is player identification information, of the magnetic card inserted into the magnetic-card inserting slot 1015; and a magnetic-information writer 1205 for writing various types of information into the magnetic card. The station control device 1201 is connected to each of the token managing device 1202, the RAM 1203, the magnetic-information reader 1204, and the magnetic-information writer 1205. Various types of information read out from the magnetic-information reader 1204 are stored in the RAM 1203 which is an individual information storage unit functioning as individual information storage means. Further, credit data corresponding to the number of tokens dropped in the token drop-in unit 1013 is also stored in the RAM 1203. Handling of tokens by a player is carried out by increasing or decreasing the credit data. The station control device 1201 is also connected to each of units such as: the display 1011 and the touch panel 1012 (shown in FIG. 2) arranged in the station 1010; a token drop-in sensor (not shown) for detecting the token dropped in via the token drop-in unit 1013; and a magnetic-card driving device (not shown) for driving the magnetic card inserted into the magnetic-card inserting slot 1015.

Furthermore, as shown in FIG. 3 and FIG. 4, the station control device 1201 of each station 1010 is connected to the main control device 1101 on the game machine main body side, enabling data communication necessary between these components.

The main control device 1101 of the main control unit 1100, in order to realistically reproduce an actual horse race when holding a race, changes a movement control content of each model horse for each race according to various types of data such as a parameter of each horse. Then, the movement control content is determined before the start of a race, and the movement of the model horse is controlled according to the resultant movement control content. Concretely, before the start of a race, the main control device 1101 of the main control unit 1100 reads out various types of parameters of horses competing in the current race and data such as turf condition, from the ROM 1107, so as to determine the order of arrival for the current race. It is noted that only a first place horse and a second place horse affect the payout of the token to the player, and thus, it is not necessary to determine the orders of all the horses competing in that race and it suffices to determine at least the first place horse and the second place horse. In this case, the movement of the other horses is controlled according to the various types of parameters so that the other horses do not arrive at the finish line first or second. Order of arrival data, the parameter of each horse, etc., determined by the main control device 1101 are forwarded to the movement control device 1102.

The movement control device 1102 that receives the data from the main control device 1101 executes the movement control program recorded in a ROM (not shown) so as to perform movement control on each horse. The movement control device 1102 executing the movement control program calculates a moving pattern of each horse from the parameter, etc., of each horse, and transmits a control command to each control chip 1022 so that each model horse 1060 is moved according to the resultant moving pattern. Concretely, in order to generate a magnetic field allowing each model horse 1060 to move according to the moving pattern of each horse, a control command is transmitted to the control chip of each magnetic field generation-use circuit board. Each control chip 1022 that receives the control command controls a current that passes through each coil so that a magnetic force that pulls a south pole of a permanent magnet of each model horse 1060 along a planned moving route of each model horse 1060 is sequentially generated. Thereby, each model horse 1060 can be moved along the planned moving route. As a result, each model horse 1060 of which the movement is controlled by the movement control device 1102 develops the race in the play field.

[Pusher Game Machine 2000]

Next, the token-operated game machine 2000 will be explained.

The token-operated game machine 2000 is a pusher game machine.

FIG. 5 is an explanatory view for explaining the configuration of a station unit ST in the pusher game machine 2000.

In the pusher game machine 2000, four satellite units SA are arranged to surround a center drawing apparatus (not shown). Each satellite unit SA is provided with the four station units ST as game apparatus, and each player is to individually play a game at each station unit ST. Moreover, each satellite unit SA is provided with one satellite drawing apparatus 2001, and around the satellite drawing apparatus 2001, each station unit ST is lined and placed.

The station unit ST is configured mainly by: a token drop-in mechanism (drop-in unit) 2100; a play field 2500; a station control unit (not shown); and a display unit 2700. In the station unit ST, the token drop-in mechanism 2100 is placed on an upper near side, the display unit 2700 that functions as display means is placed on an upper far side, and the play field 2500 is placed at an upper center. The “near side” means a side on which the player is positioned during the game, the “far side” means a side opposite to the side on which the player is positioned during the game, and the “center” means an area between the “near side” and the “far side.”

The token drop-in mechanism 2100 is a mechanism for the player to drop a token M into the pusher game machine 2000 during the game. The token M dropped into the token drop-in mechanism 2100 is conveyed via a token conveyance route (not shown) in the interior of the cabinet of the station unit ST to a lift-up hopper, and the resultant token M is temporarily retained by the lift-up hopper. The lift-up hopper includes: a token retaining unit for accumulating the token M; the lift-up unit for lifting up the token M to a predetermined height; and a token discharge unit (discharge unit) for discharging the token M that is lifted up at a predetermined timing. At a discharge opening of the token discharge unit, arranged is a token discharge route 2400 for leading the discharged token M to the play field 2500 in a manner to laterally swing. An upper end of the lift-up unit is placed above the play field 2500. As a result, the token discharge unit arranged at the upper end of the lift-up unit is placed above the play field 2500. Therefore, the token M temporarily accumulated in the token retaining unit arranged below the play field 2500 is raised above the play field 2500 by the lift-up unit, and thereafter, the raised token M is exited via the token discharge route 2400 from the token discharge unit, out onto the play field 2500.

Within the play field 2500, arranged mainly are: a main table 2501 that is a token mount table for retaining thereon the token M, and the pusher unit 2510 as a token extruding member which is mounted on the main table 2501. The pusher unit 2510 includes: a top surface (this is called a sub table) for retaining thereon the token M; a sloping table on which the token M that falls from the sub table slides; and a push-forward wall that pushes forward the token M retained on the main table 2501. Moreover, the pusher unit 2510, which is arranged to enable sliding on the main table 2501 in the play field 2500, makes a back-and-forth slide movement in a constant cycle or an arbitrary cycle. A part (far side) of the pusher unit 2510 is housed in a housing part (described later) arranged beneath the display unit 2700. The pusher unit 2510, which slides to come out of and into the housing part, makes a back-and-forth reciprocating movement.

With the sub table, a frame member of the display unit 2700 comes into contact in a manner to enable sliding. Therefore, when the pusher unit 2510 moves to a direction in which it is housed in the housing part, the token M on the sub table is pushed forward by the frame member. By the pushing forward, some tokens M on the sub table fall onto the sloping table. Some tokens M that fall from the sub table enter into an opening (this is called a “chucker”) that is a token pass-through opening arranged on the sloping table. The remaining tokens M fall directly onto the main table 2501 and are retained on the main table 2501.

The tokens M on the main table 2501, similar to the tokens M on the sub table, are pushed forward by the slide movement of the pusher unit 2510. That is, the pusher units 2510 are seamlessly mounted on the main table 2501, and thus, when the pusher unit 2510 is moved in a discharge direction from the housing part, the tokens M on the main table 2501 are pushed forward by the push-forward wall on the front surface of the pusher unit 2510. By the pushing forward, some tokens M on the main table 2501 fall. Out of the tokens M that fall, the token M that falls from an end on the player side (this is called a “front end”) to a token fall groove is paid to the player, and the other tokens M, e.g., the tokens M that fall from both sides (these are called “side ends”) of the main table 2501 are stocked in a predetermined retaining unit within the station unit ST.

Besides, as shown in FIG. 5, the station unit ST includes a ball drop-in mechanism 2800 on at least one side. The ball drop-in mechanism 2800 is configured to drop balls B1 and B2 that are spherical objects (as differently shaped objects described later) into the play field 2500, and includes a ball drop-in slope 2801 and a ball drop-in position drawing mechanism 2810. The balls B1 and B2 are objects for drawing used for executing a bingo game described later.

The ball drop-in slope 2801, which is configured to lead the balls B1 and B2 dropped in from a ball carrier 2520 described later to the ball drop-in position drawing mechanism 2810 by gravity, is formed as a downhill slope. The ball drop-in position drawing mechanism 2810 is configured to draw a position on the play field 2500 onto which the balls B1 and B2 are dropped. Thus, the balls B1 and B2 dropped in from the ball carrier 2520 described later to the station unit ST are dropped in via the ball drop-in slope 2801 and the ball drop-in position drawing mechanism 2810 onto the play field 2500.

As shown in FIG. 5, the station unit ST includes a ball transportation mechanism 2900 on at least one side. The ball transportation mechanism 2900 is configured, when the balls B1 and B2 fall from the main table 2501 in the play field 2500 onto the token fall groove arranged on the near side, to transport the balls B1 and B2 to the satellite drawing apparatus 2001, and includes a ball conveying route (not shown), a ball transporting unit 2910, and a ball transporting unit traveling slope 2901. The ball conveying route is arranged below the front end of the main table 2501, and leads the balls B1 and B2 that fall from the front end to the ball transporting unit 2910. The ball transporting unit 2910 is configured to transport the balls B1 and B2 received via the ball conveying route, to the satellite drawing apparatus 2001, and travels on the ball transporting unit traveling slope 2901 according to control of the control unit of the station unit ST. The balls B1 and B2 transported to the satellite drawing apparatus 2001 are handed over to the ball carrier 2520.

Moreover, the station unit ST includes a token payout mechanism 2030, and as a result of the token payout mechanism being driven, the tokens M of which the number of pieces is equal to that of the tokens M that fall onto the token fall groove from the front end of the main table 2501 are discharged to the retaining unit 2101 of the token drop-in mechanism 2100.

Next, a control system of the pusher game machine 2000 will be explained.

FIG. 6 is a block diagram showing a main configuration of a game control system of the pusher game machine 2000. In this block diagram, for the sake of explanation, configurations of a drive control system for driving each unit according to the game progress and any other systems are omitted.

The game control system of the pusher game machine 2000 is configured mainly by: a control unit 2600 at the station unit ST; a control unit 2610 of the satellite drawing apparatus 2001; and a control unit 2620 of the center drawing apparatus 2002. The control unit 2600 of the station unit ST mainly assumes a role of overall process control of a slot game and a bingo game described later, the control unit 2610 of the satellite drawing apparatus 2001 mainly assumes a role of control of a physical drawing of the bingo game and transportation control of the balls B1 and B2, and the control unit 2620 of the center drawing apparatus 2002 mainly assumes a role of a single-unit jackpot drawing control described later and overall control of the pusher game machine 2000.

The control unit 2600 of the station unit ST is configured mainly by: a control device 2601; a ROM 2602; a RAM 2603; and a communication device 2604. The control device 2601 executes various types of programs stored in the ROM 2602 so as to perform various types of controls. The ROM 2602 stores, for example, execution programs for various types of controls that should be performed in the control unit 2600 of the station unit ST. The RAM 2603 is for temporarily storing various types of data or information. The communication device 2604 is for performing data communication with the control unit 2610 of the satellite drawing apparatus 2001. Although not shown, the station unit ST includes a performance unit, such as a speaker and an illuminating device, used for various types of performances, and the control device 2601 controls these performance units so as to carry out various types of performances.

The control unit 2610 of the satellite drawing apparatus 2001 is configured mainly by: a control device 2611; a ROM 2612; a RAM 2613; a station-side communication device 2614; and a center-side communication device 2615. The control device 2611 executes various types of programs stored in the ROM 2612 so as to perform various types of controls. The ROM 2612 stores, for example, execution programs for various types of controls that should be performed in the control unit 2610 of the satellite drawing apparatus 2001. The RAM 2613 is for temporarily storing various types of data or information. The station-side communication device 2614 is for performing data communication with the control unit 2600 of the each station unit ST belonging to the satellite unit SA. The center-side communication device 2615 is for performing data communication with the control unit 2620 of the center drawing apparatus 2002. Although not shown, the satellite unit SA includes a performance unit, such as a speaker and an illuminating device, used for various types of performances, and the control device 2611 controls these performance units so as to carry out various types of performances.

The control unit 2620 of the center drawing apparatus 2002 is configured mainly by: a control device 2621; a ROM 2622; a RAM 2623; a communication device 2624; and an external communication device 2625. The control device 2621 executes various types of programs stored in the ROM 2622 so as to perform various types of controls. The ROM 2622 stores, for example, execution programs for various types of controls that should be performed in the control unit 2620 of the center drawing apparatus 2002. The RAM 2623 is for temporarily storing various types of data or information. The communication device 2624 is for performing data communication with the control unit 2610 of each satellite unit SA. The external communication device 2625 is for performing data communication via a LAN with an external device such as a gaming arcade server 5000. Although not shown, the center drawing apparatus 2002 includes a performance unit, such as a speaker and an illuminating device, used for various types of performances, and the control device 2621 controls these performance units so as to carry out various types of performances.

In the above-described configuration, in the pusher game machine 2000, in addition to the pusher game, a slot game is performed by displaying a slot game screen as shown in FIG. 7 on the display unit 2700, and a bingo game is performed by displaying a bingo game screen as shown in FIG. 8 on the display unit 2700. In the pusher game machine 2000, a single-unit jackpot drawing using the center drawing apparatus 2002 is also performed. On the display unit 2700, a single-unit accumulated token count indicating the number of pieces to be paid out in a single-unit jackpot drawing described later and a total accumulated token count indicating the number of pieces to be paid out in a total jackpot drawing described later are displayed.

The slot game is a digital drawing game in which the control unit 2600 at the station unit ST mainly performs a drawing digitally. This slot game is started under the condition that the token M enters into any one of chuckers arranged on the sloping table at the pusher unit 2510. The slot game screen shown in FIG. 7 is displayed on the display unit 2700 during a period when the bingo game described later does not progress. When the token M enters into any one of the chuckers and thereby the slot drawing start condition is satisfied, the control unit 2600 performs display control to rotate three dice-shaped slots DS. In the digital drawing of the slot game, the control unit executes a predetermined drawing program, and checks a generated random number in reference to a predetermined winning table so as to determine whether to win any payout-symbol combination or lose. Thereafter, where a winning payout-symbol combination is determined, the control unit 2600 performs display control to stop the rotation of the three dice-shaped slots DS so that a combination of symbols relating to the winning payout-symbol combination is stopped and displayed on the display unit 2700.

In the present embodiment 1, as a payout-symbol combination for a digital drawing, prepared are: a minor payout-symbol combination A in which three tokens are supplied to the play field 2500; a minor payout-symbol combination B in which eight tokens are supplied to the play field 2500; a ball supply payout-symbol combination in which the ball B1 is supplied to the play field 2500; a normal bonus payout-symbol combination in which thirty tokens are supplied to the play field 2500; a probability-change bonus payout-symbol combination in which thirty tokens are supplied to the play field 2500 and a winning table at which a winning probability is set to be higher is used in subsequent digital drawings; a direct satellite payout-symbol combination in which the ball B1 is directly supplied to the satellite drawing apparatus 2001; a direct center payout-symbol combination in which the ball B1 is directly supplied to the center drawing apparatus 2002, and other payout-symbol combinations. The winning probability of each of these payout-symbol combinations is set to be lowered according to the above-described order. It is noted that, which payout-symbol combination is prepared or to which winning probability of each of the payout-symbol combinations is set is determined arbitrarily. For example, it may be possible to configure that various benefits are given to a player such as direct payout of tokens M to the player. Then, when these payout-symbol combinations are won, the control device 2601 of the station unit ST controls the speaker or the illumination device, etc., so as to carry out individual performance to liven up the winning.

The bingo game is a physical drawing game which progresses by a physical drawing using two types of balls B1 and B2 and the satellite drawing apparatus 2001. The bingo game progresses by the control unit 2610 of the satellite drawing apparatus 2001 and the control unit 2600 at the station unit ST. In the bingo game, the control unit 2610 of the satellite drawing apparatus 2001 mainly controls a drawing for determining winning bingo numbers of the bingo game. The control unit 2600 of each of the station units ST belonging to the satellite unit SA including the satellite drawing apparatus 2001 is mainly in charge of controlling the performance of the bingo game, a decision of the establishment of BINGO, and so on. In the present embodiment 1, the balls B1 and B2 are moved by the satellite drawing apparatus 2001, by which a physical drawing is performed in which one winning bingo number (a winning target) is selected from a plurality of bingo numbers (drawing targets) different from each other. In the physical drawing of the present embodiment 1, one winning bingo number is selected from the bingo numbers of “1” through “9”. Then, array information of the bingo card having these bingo numbers of “1” through “9” arrayed in a matrix is generated individually for each of the station units ST by the control unit 2600 that is as an array-information producing unit which functions as array-information producing means for the station unit ST, for example. Thereafter, a bingo card image BC in which images of the bingo numbers of “1” through “9” (drawing target images) are arrayed according to the array information is displayed on the display unit 2700 of each of the station units ST, as shown in FIG. 8. Then, when the BINGO is established, the control device 2601 of the station unit ST or the control device 2611 of the satellite unit SA each controls the speaker, the illuminating device, etc., so as to carry out an individual performance to liven up the establishment of BINGO.

In the single-unit jackpot drawing, when either one of conditions under which the single-unit jackpot drawing is started is satisfied, i.e., the balls B1 and B2 are thrown into a winning spot to which a right of starting a single-unit jackpot drawing in the center drawing apparatus 2002 in the physical drawing in the satellite drawing apparatus 2001 in the above-described bingo game is assigned, or the center combination is directly won in the above-described slot game, the control device 2621 of the control unit 2620 in the center drawing apparatus 2002 executes a single-unit jackpot execution program stored in the ROM 2622 so as to start the single-unit jackpot drawing. Then, in the center drawing apparatus 2002, the ball B1 is moved thereby to perform the physical drawing that determines whether a single-unit jackpot award is won or lost (including a case where awards other than the single-unit jackpot award are won). When the single-unit jackpot award is won, the control device 2621 of the center drawing apparatus 2002 controls the speaker, the illuminating device, etc., so as to carry out an individual performance to liven up the winning of the single-unit jackpot award.

Moreover, when the single-unit jackpot award is won, the control device 2621 reads out the single-unit JP retaining count data that is payout amount data from the RAM 2623, and performs a process for supplying the tokens M having the number of pieces indicated by a count value of that data, to the play field 2500 of the station unit ST that has satisfied the condition under which the jackpot drawing is started. At this time, another option would be: a token supply command is output to the control device 2601 of the control unit 2600 at the station unit ST from the control device 2621, and under the control of the control device 2601, the token M is supplied to the play field 2500 by using a method similar to a normal token supply process. In this case, however, the number of pieces of tokens to be supplied when the single-unit jackpot award is won is obtained by accumulatively adding the number of pieces equivalent to a part of the number of pieces of tokens to be dropped into all the station units ST (for example, 0.03 pieces) from a time when the single-unit JP retaining count data is reset to an initial value (for example, 500 pieces), therefore, it is a great number. For this reason, instead of the normal token supply process, a process using an original token supply mechanism may be optionally adopted. This is preferable as a performance carried out when the single-unit jackpot award is won. Moreover, when the single-unit jackpot award is won, the control device 2621 resets the single-unit JP retaining count data stored in the RAM 2623, to the initial value.

Moreover, on the performance panel 3011, various types of information such as a total accumulated token count indicating the number of pieces of payouts in the total jackpot drawing described later are displayed.

Inside the cabinet 3002, three reels that as three varying display units of which the outer peripheral surface is printed with a plurality of types of symbols are assembled. The three reels (hereinafter, in the order of a “left reel”, a “middle reel”, and a “right reel”) are each rotated and driven by a reel drive motor (not shown) configured by a stepping motor. These reels are printed with a plurality of types of symbols such as “white 7”, “blue 7”, “green 7”, “red 7”, “cherry”, and “blank” in a predetermined order. In the present embodiment 1, the symbol of “blank” configures neither one of the payout-symbol combinations. A main control circuit board on which electronic circuits are formed by various types of electronic components such as a CPU and a ROM, a token payout device having a token hopper capable of containing a large number of pieces of tokens, an internal speaker, and any other similar components are also assembled.

FIG. 10 is a detailed front view showing part of the front panel 3003.

Symbols formed by about three images at a predetermined rotation position of each reel are to be visually recognized by a player through the display window 3004. In this display window 3004, five winning lines IL are depicted across all of the reels. When symbols relating to a payout-symbol combination corresponding to an award group previously defined on these winning lines IL become all the same in a combination (hereinafter, this is simply referred to as the “symbols become all the same in a payout-symbol combination”), a game value is imparted to a player, such as the tokens are paid out to the token receiving tray 3010 and a current period is moved to a special game period during which a special game can be played. It is noted that, in the slot machine 3000 according to the embodiment 1, the five winning lines IL are arranged; however, the number of winning lines may be optionally increased or decreased. Moreover, the winning line may suffice to be visually recognized by a CPU 17 a, described later, for performing stop control of the slot machine, rather than to be visually recognized by the player.

The count display unit 3014 is provided with a credit display 3014 a, a bonus-count display 3014 b, a token payout count display 3014 c, etc.

The BET operation unit 3015 is configured by two buttons, i.e., a 1BET button 3015 a and a max BET button 3015 b.

FIG. 11 is a control block diagram relating to a main configuration of the slot machine 3000. The main control unit 3100 of the slot machine 3000 includes: a control device 3101; a reel control device 3102 for performing drive control for the three reels; a storage device 3103 in which various types of programs necessary for the game, various types of databases, etc., are stored; a display control device 3104 for performing display control of the count display unit 3014; an illumination control device 3105 for controlling illumination of the performance panel 3011, etc.; an audio control device 3106 for controlling a sound output from the speaker 3009; and an external communication device 3107 for performing a data communication with an external apparatus such as the gaming arcade server 5000 via a LAN. The main control device 1101 is connected not only to these devices but also to, for example, the token drop-in sensor 3022, the BET operation unit 3015, and the token payout device 3018.

Next, a flow of the game of the slot machine 3000 will be explained.

Before the game is started, as a preparation, a player first needs to drop a token into the token drop-in opening 3005. When a token is dropped by the player into the token drop-in opening 3005, the token passes through a passage (not shown) and falls onto the token hopper. In this passage, various components are arranged such as a fall opening through which a token smaller than a standard falls back to the token payout opening 3010 a, a token block solenoid for returning or permitting the token to the token payout opening 3010 a by blocking the passage of the token, and a token drop-in sensor 3022 configured by, for example, a photo sensor for detecting the passed tokens one by one. A token detection signal output from the token drop-in sensor 3022 that detects the token is forwarded to the control device 3101 of the main control unit 3100. In receipt thereof, by means of the display control device 3104, the control device 3101 performs control to increase a display count value by one on the credit display 3014 a and to increase a value of credit count data stored in the storage device 3103 by one. Normally, a plurality of pieces of tokens are dropped in at once so as to increase the number of pieces of credit to a certain extent. When the player operates the BET operation unit 3015 to perform a bet operation, the control device 3101 decreases the value of the credit count data stored in the storage device 3103 by as much as the number of pieces to be bet, and at the same time, performs control to decrease the display count value on the credit display 3014 a by as much as the number of pieces to be bet. Moreover, the control device 3101 recognizes the winning line IL that has become effective according to the number of pieces to be bet. It is noted that, unless the symbols become all the same in the payout-symbol combination on the effective winning line IL, the winning is not granted even when the symbols become all the same in the payout-symbol combination on an ineffective winning line IL.

When the start button 3006 is operated by the player, the control device 3101 that is a start-command receiving unit executes a start-command receiving program stored in the storage device 3103 thereby to function as start-command receiving means so as to receive a varying-display start command from its start button 3006. The control device 3101 that has received this varying-display start command, first, starts rotation drive of all the reels by the reel control device 3102. Further, the control device 3101 that has received the varying-display start command executes an award-group drawing program stored in the storage device 3103 so as to perform an internal drawing. In this case, the control device 3101 functions as means for performing an internal drawing to determine a winning in which any award group is selected out of a plurality of award groups or a loss in which neither award group is selected. The internal drawing is performed by checking random number data forwarded from a random-number generating circuit with a value on an award group drawing table stored in the storage device 3103. On this award-group drawing table, each random number is associated with any award group or the loss. As a result of such an association, any one of the award groups is won at an individual predetermined probability, or the loss occurs at a predetermined probability.

Rotation positions of the reels that start the rotation drive are respectively detected by a reel position sensor (not shown). The reel control device 3102 performs an arithmetic operation on the rotation speed of the reel based on an output signal from each reel position sensor. When the rotation speed of the reel is stabilized, the reel control device 3102 becomes capable of recognizing a position of each symbol on each reel based on the output signal from each reel position sensor. Then, the control device 3101 executes a stop control program stored in the storage device 3103, and based on a drawing result of the above-described internal drawing, performs stop control of the reel by the reel control device 3102 so that a combination of predetermined symbols is stopped and displayed on the winning line. Concretely, when any one of the award groups is won by the internal drawing, the control device 3101 performs stop control so that a combination of symbols relating to a payout-symbol combination corresponding to the award group that has won is stopped and displayed on the winning line IL. On the other hand, in the case of the loss as a result of neither one of the award groups being selected by the internal drawing, the control device 3101 performs stop control so that a combination of symbols corresponding to neither award group is stopped and displayed on the winning line IL.

In a normal game, the internal drawing is performed by using an award-group drawing table corresponding to that normal game. Examples of award groups that may be won by the internal drawing of this normal game include token payout awards of: a cherry award corresponding to a cherry combination formed by “cherry-ANY (any symbol pattern)-ANY (any symbol pattern)”; an ANY7 award corresponding to an ANY7 combination formed by a plurality of colors of “7” that are “ANY7 (any color of “7”)-ANY7 (any color of “7”)-ANY7 (any color of “7”)”; a white 7 award corresponding to a white 7 combination formed by “white 7-white 7-white 7”; a blue 7 award corresponding to a blue 7 combination formed by “blue 7-blue 7-blue 7”; a green 7 award corresponding to a green 7 combination formed by “green 7-green 7-green 7”; and a red 7 award corresponding to a red 7 combination formed by “red 7-red 7-red 7.” When any one of the token payout awards is won as a result of the internal drawing and the symbols corresponding thereto become all the same in a winning combination on the winning line IL, the control device 3101 causes the token payout count display 3014 c of the count display unit 3014 to display the number of pieces of tokens to be paid out corresponding to the winning award. Then, the control device 3101 performs a token payout process for paying out the number of pieces of tokens corresponding to the winning award. Concretely, the control device 3101 increases a value of the credit count data stored in the storage device 3103 by as much as the number of pieces of tokens to be paid out, and at the same time, performs control to increase the token credit on the credit display 3014 a by as much as the number of pieces of tokens to be paid out. When a token credit upper limit value is exceeded, the exceeded amount is paid out to the token receiving tray 3010 from the token payout opening 3010 a by the token payout device 3018. According to the order in which the above-described award groups are described, the number of pieces of tokens that are paid out is larger.

[Jackpot System]

Next, the total jackpot drawing performed in the whole system will be explained.

FIG. 12 is a control block diagram of the management server 4000 for performing progress control of the total jackpot drawing which is performed together with each gaming arcade server 5000.

The management server 4000 is configured mainly by a control device 4001, a storage device 4002 and an external communication device 4003. The storage device 4002 stores various types of control programs, and stores total accumulated token count data that is payout amount data of the whole system. The external communication device 4003 is for performing data communication via a WAN with an external apparatus such as the gaming arcade server 5000 at each gaming arcade.

FIG. 13 is a control block diagram of the gaming arcade server 5000 for managing a system within each gaming arcade and also performing data communication between the management server 4000 and each token-operated game machine at the gaming arcade.

The gaming arcade server 5000 is configured mainly by a control device 5001, a storage device 5002, an external communication device 5003 and an intra-arcade communication device 5004. The storage device 5002 stores various types of control programs. The storage device 5002 stores intra-arcade accumulated token count data that is a part of the tokens consumed in the token-operated game machines 1000, 2000, and 3000 within the gaming arcade constituting the game system, and also stores the total accumulated token count data forwarded from the management server 4000. The external communication device 5003 is for performing data communication via a WAN with an external apparatus such as the management server 4000. The external communication device 5003 is for performing data communication via a LAN with each of the token-operated game machines 1000, 2000, 3000, etc.

FIG. 14 is a sequence flowchart showing a flow of the total jackpot drawing in the present embodiment 1. In FIG. 14, for the sake of explanation, only one token-operated game machine and one gaming arcade server are described.

In the game system, when a player consumes the tokens in each of the token-operated game machines 1000, 2000, and 3000, data indicating a consumption amount is forwarded to the gaming arcade server 5000 located in its gaming arcade.

Based on the data forwarded from each of the token-operated game machines 1000, 2000, and 3000, the control device 5001 of the gaming arcade server 5000 accumulatively stores, as the intra-arcade accumulated token count data, a part of the tokens (for example, 0.01 pieces) consumed by the player in the token-operated game machines 1000, 2000, and 3000 within the gaming arcade connected to this gaming arcade server 5000 into the storage device 5002. Then, the control device 5001 transmits the intra-arcade accumulated token count data in the storage device 5002 to the management server 4000 at a predetermined timing. It is noted that the intra-arcade accumulated token count data to be transmitted this time is as much as that accumulatively stored between a last transmission time point and a current transmission time point.

At each reception of the intra-arcade accumulated token count data forwarded from each gaming arcade server 5000, the management server 4000 accumulatively adds the number of pieces of tokens indicated by the received data to the total accumulated token count data in the storage device 4002. Thereby, a part of the number of pieces of tokens (for example, 0.01 pieces) consumed in all the token-operated game machines constituting the present game system is added up as the total accumulated token count data. In the present embodiment 1, for example, an initial value of the total accumulated token count data is 1000 pieces of tokens and a part of the number of pieces of tokens consumed by the player is accumulatively added to this initial value.

In the present embodiment 1, also in the above-described pusher game machine 2000, the single-unit jackpot drawing is performed, and the accumulated token count data of the single-unit jackpot drawing is obtained by calculation only from the number of pieces of tokens consumed in that pusher game machine 2000. On the other hand, the accumulated token count data of the total jackpot drawing managed and run by the management server 4000 is obtained by calculation from the number of pieces of tokens consumed by all the token-operated game machines constituting the present game system. As a result, it is possible to increase the number of pieces of tokens to be paid out to a winner when the winner wins the jackpot drawing.

A specific process flow will be now explained. The control device 4001 of the management server 4000 receives the intra-arcade accumulated token count data transmitted from each gaming arcade server 5000 at a predetermined timing (for example, at intervals of 10 minutes) thereby, first, to perform a process for accumulatively adding to the total accumulated token count data in the storage device 4002, as shown in FIG. 14. Thereafter, the total accumulated token count data stored in the storage device 4002 at this time point is transmitted to the gaming arcade server 5000 that is a transmission source of the intra-arcade accumulated token count data that is received immediately before. The gaming arcade server 5000 that receives the total accumulated token count data transmits the same data to each of the token-operated game machines 1000, 2000, and 3000. Then, in each of the token-operated game machines 1000, 2000, and 3000 that receive that data, respective displays of the total accumulated token count are updated based on the received total accumulated token count data. In the present embodiment 1, the total numbers of pieces of accumulated tokens are individually displayed in each token-operated game machine. In this case, a display device for displaying the total accumulated token count may be arranged within the gaming arcade in order to omit the individual display in each token-operated game machine.

The total jackpot drawing in the present embodiment 1 is started under the condition that the management server 4000 receives the intra-arcade accumulated token count data from the gaming arcade server 5000.

In the present embodiment 1, when receiving the intra-arcade accumulated token count data from each gaming arcade server 5000, the control device 4001 of the management server 4000 executes the total jackpot drawing program so as to perform a gaming-arcade-drawing as a group drawing firstly. In the gaming-arcade-drawing, a drawing is performed so as to determine whether the gaming arcade of the transmission source of that data is won or lost by checking the generated random number in reference to the predetermined winning table. When the winning is determined in the gaming arcade drawing, the control device 4001 transmits winning data to the effect that the gaming arcade server 5000 is won in the gaming arcade drawing, to the gaming arcade server 5000 that has transmitted the intra-arcade accumulated token count data that is a condition for starting the drawing.

Another method therefor may include the following, for example. That is, when receiving the intra-arcade accumulated token count data from any one of the gaming arcade servers 5000, the control device 4001 of the management server 4000 executes the total jackpot drawing program so as to perform the gaming arcade drawing to determine which one of the gaming arcades win or neither one of the gaming arcades win by checking the generated random number in reference to the predetermined winning table. In this gaming arcade drawing, the winning gaming arcade may not necessarily be determined. Therefore, there is a case where neither one of the gaming arcades wins in the gaming arcade drawing. When winning of any one of the gaming arcades is determined in the gaming arcade drawing, the control device 4001 transmits the winning data to the effect that the gaming arcade server 5000 is won in the gaming arcade drawing, to the gaming arcade server 5000 (of the gaming arcade) relating to that winning.

It is noted that the condition for starting the total jackpot drawing is not limited to the above-described condition but may include any condition as long as it may occur at suitable time intervals. In particular, according to the present embodiment 1, it is possible to provide a condition which is not related to a game play played by a player with each of the token-operated game machines 1000, 2000, 3000. For example, a condition that a predetermined constant time elapses may be regard as a total jackpot drawing start condition. Further, for example, arrival of a predetermined time may be regard as the total jackpot drawing start condition or instructions for starting a game by an employee of a gaming arcade may be regard as the total jackpot drawing start condition.

The gaming arcade server 5000 that has received the winning data performs a process for determining, as a winner for the total jackpot award, which one of the players who plays in the token-operated game machines 1000, 2000, and 3000 connected to the gaming arcade server 5000 in the gaming arcade. In this process, it is informed that there is a winner for the total jackpot drawing within the gaming arcade. In this way, a sense of expectation (such as any player can be a winner) is grown and an interest in who has won the game is developed. In doing so, an advance notification performance (hereinafter, referred to as a “total jackpot performance”) is carried out for getting attention of, for example, the player and the audience in the whole gaming arcade. This total jackpot performance needs to be carried out simultaneously at all the token-operated game machines 1000, 2000, and 3000 in the gaming arcade, and in this case, due to a certain reason related to the game progress at each of the token-operated game machines 1000, 2000, and 3000, a timing at which the performance is carried out (total jackpot performance timing) needs to be adjusted. Because at each of the token-operated game machines 1000, 2000, and 3000, the game is individually progressed, and thus, depending on a certain progress situation, the progress of that game may be impeded by the total jackpot performance, resulting in an undesirable case where a sense of enjoyment of the player is greatly decreased.

For example, in the horse-racing game machine 1000, if the total jackpot performance is suddenly started at a time when a race is reproduced by using the field unit 1002, the excitement of the game originally provided in that horse-racing game machine is significantly decreased, hence not preferable. Further, in the pusher game machine 2000, if the total jackpot performance is suddenly started in the middle of a drawing where a large amount of tokens to be paid out can be expected such as in a physical drawing of the bingo game and the single-unit jackpot drawing, the excitement of the game originally provided in that pusher game machine is significantly decreased, hence not preferable. Moreover, in the slot machine 3000, if the total jackpot performance is suddenly started in the middle of the winning performance when a large amount of tokens to be paid out such as in the green 7 award and the red 7 award is determined, the joy of the player is significantly decreased, hence, not preferable.

On the other hand, at each of the token-operated game machines 1000, 2000, and 3000, there is a timing at which adverse effect (such as decreasing the enjoyment originally provided in that token-operated game machine) is less caused even when the individual game progress is impeded by the total jackpot performance. For example, in the horse-racing game machine 1000, at a timing used for betting a token by the player, i.e., a timing used for purchasing a betting ticket, the adverse effect is less caused. Thus, this timing is suitable for starting the total jackpot performance. Further, for example, in the pusher game machine 2000, at a timing except for a middle of a drawing where a large amount of tokens to be paid out can be expected or a middle of the winning performance therefore, the adverse effect is less caused. Thus, this timing is suitable for starting the total jackpot performance. Moreover, for example, in the slot machine 3000, at a timing from a first slot game is ended to a subsequent slot game is started, concretely, from a time after the loss is determined in the last slot game or after the winning performance is ended to a time before the start button 3006 of the subsequent slot game is operated, the adverse effect is caused less. Thus, this timing is suitable for starting the total jackpot performance.

In each of the token-operated game machines 1000, 2000, and 3000 of the present embodiment 1, the game progress situations illustrated here are set in advance as situations where the total jackpot performance can be carried out.

FIG. 15 is a sequence flowchart for explaining a determining process of the total jackpot performance timing.

The gaming arcade server 5000 that has received the winning data, first, inquires all the token-operated game machines 1000, 2000, and 3000 through the LAN of a timing at which the game progress situation becomes capable of carrying out the total jackpot performance. In response to this inquiry, the control devices 1101, 2621, and 3101 that are timing anticipation processing units of the respective token-operated game machines 1000, 2000, and 3000 function as timing anticipation processing means, solely or working together with the other control devices 1201, 2601, and 2611, and execute a timing anticipation program so as to perform a process for predicting a timing at which each game progress situation becomes the above-described setting situation previously determined.

Then, the control devices 1101, 2621, and 3101 of the respective token-operated game machines 1000, 2000, and 3000 send total performance enabling timing information indicating the anticipated timing, back to the gaming arcade server 5000 from the external communication devices 1108, 2625, and 3107. The control device 5001 that is a total performance timing determining unit of the gaming arcade server 5000 functions as total performance timing determining means, and based on the total performance enabling timing information forwarded from each of the token-operated game machines 1000, 2000, and 3000, determines the total performance timing at which the total jackpot performance is carried out. Concretely, based on each total performance enabling timing information, an earliest timing at which the total performance enabling timings of all the token-operated game machines 1000, 2000, and 3000 overlap is specified, and the resultant timing is determined as a total performance timing. Then, information on the determined total performance timing is transmitted to each of the token-operated game machines 1000, 2000, and 3000. In each token-operated game machine that has received the information, at the determined total performance timing, the game progress is controlled so that the game progress situation at each token-operated game machine becomes the above-described predetermined setting situation where the total jackpot performance can be carried out. A specific method of controlling is as follows: the above-described setting situation is stored in each of the token-operated game machines 1000, 2000, and 3000, the stored information on the setting situation is read out to perform the game progress control, or the above-described setting situation is previously installed in a game progress control-use program, and the game progress control is performed according to a content of that program.

It is noted that, in order for the game progress situation to become the above-described setting situation at the exact timing of the total performance timing determined by the control device 5001 of the gaming arcade server 5000, it may need to perform a fine adjustment for the game progress in the individual token-operated game machines 1000, 2000, and 3000.

As examples of a method for the fine adjustment in the horse-racing game machine 1000, a reproducing time of a race reproduction movie is shortened or lengthened in a reproducing process of a race reproduction movie executed after each race is ended. Concretely, the reproducing time may be shortened or lengthened by setting a time for starting the reproduction of the race reproduction movie in a middle stage of the race or a final stage thereof.

Further, another method for the fine adjustment in the pusher game machine 2000 is as follows: in the slot game executed at each station unit ST, the fine adjustment is performed by display control to lengthen or shorten a time from which the rotation of the three dice-shaped slots DS is started until it is stopped. Concretely, a speed for reproducing video from the start of the rotation of the three dice-shaped slots DS to the stop thereof may be lengthened or shortened, for example. In this case, there is no need of editing the video itself, thus, the display process is easy.

Moreover, the method for the fine adjustment in the slot machine 3000 is as follows: the fine adjustment is performed by drive control in which a time from a start of the rotation of the three reels to a stop thereof is lengthened or shortened.

The method for the fine adjustment is not limited to those described above, and it is determined, where appropriate, depending on a game content, etc., of each of the token-operated game machines 1000, 2000, and 3000.

In particular, in a game machine in which a digital drawing is performed, a method for lengthening or shortening a time period during which drawing performance-use video is displayed is effective as in the case of the above-described pusher game machine 2000.

It is noted that the method for determining the total performance timing is not limited to those described above.

For example, the control device 5001 that is a performance timing determining unit of the gaming arcade server 5000 is functioned as performance timing determining means. In doing so, rather than inquiring each of the token-operated game machines 1000, 2000, and 3000 of the total performance enabling timing, the total performance timing is determined according to a predetermined total performance timing determining condition. Then, the determined total performance timing is transmitted to each of the token-operated game machines 1000, 2000, and 3000, and the game progress control is performed in each token-operated game machine so that the game progress situation at each token-operated game machine becomes the above-described predetermined setting situation in which the total jackpot performance can be carried out at the determined total performance timing. This method is effective particularly when the token-operated game machine constituting the present game system is high in the degree of freedom of the control of the game progress situation.

When the total performance timing determined by the gaming arcade server 5000 arrives, as shown in FIG. 14, the control device 5001 of the gaming arcade server 5000 performs a player presence confirming process for recognizing the players who play at each of the token-operated game machines 1000, 2000, and 3000. Concretely, all the token-operated game machines 1000, 2000, and 3000 are inquired through the LAN of whether a player is present at each game machine. In the token-operated game machines 1000, 2000, and 3000 that have been inquired, the player presence confirming process according to the respective game content is performed.

Since the player is able to play the game with each of the plurality of stations in the horse-racing game machine 1000, a process for confirming whether the player who plays the game is present at each of the stations is performed. The confirmation method includes a method for confirming whether a player is present at each station, for example, based on a timing when the ID code, that is, the player identification information, is read out from the magnetic card inserted into the magnetic-card inserting slot 1015.

More specifically, the station control device 1201 stores in the RAM 1203 identification information reading-out timing information as decision information for specifying a timing when the magnetic-information reader 1204 reads out the ID code from the magnetic card at a timing when the player inserts the magnetic card into the magnetic-card inserting slot 1015 or at a subsequent predetermined timing. This identification information reading-out timing information may be data itself indicating a timing when the ID code is read out (time data) or flag information. Thereafter, upon receipt of an inquiry for confirming the player presence, the station control device 1201, which is a decision information detecting unit, functions as decision information detecting means and determines on the basis of the identification information reading-out timing information stored in the RAM 1203 whether a time elapsed from the latest timing of reading out the ID code to the present point in time passes over a predetermined constant time (specified period). Where the identification information reading-out timing information is data itself indicating a timing when the ID code is read out (time data), a determination may be made by whether a difference between a time indicated by the data and the present point in time is smaller than a predetermined time. Further, where the identification information reading-out timing information is the flag information, for example, survival time of the flag information is set to be a constant time predetermined as described above (specified period) and a determination may be made by confirming whether the flag information is provided (survival). As described above, a confirmation method based on the identification information reading-out timing information can be utilized in a game apparatus which controls game progress according to individual information corresponding to player identification information read out from an identification information storing medium which stores the player identification information.

Further, since the player is able to play the game with each of the plurality of station units also in the pusher game machine 2000, a process for confirming whether a player who plays the game is present at each of the station units is performed. The confirmation method includes, for example, a method for deciding that a player is present at the station unit having tokens on the retaining unit 2101 of the token drop-in structure 2100. More specifically, a sensor which is a decision information detecting unit functioning as decision information detecting means for detecting the presence of the tokens on the retaining unit 2101 is provided. When the sensor determines that a token is present on the retaining unit 2101, a determination is made that the player who plays a game is present. This confirmation method can be utilized in a game apparatus which is provided with a retaining unit for retaining tokens used by a player for playing a game.

Further, since the player plays the game alone in the slot machine 3000, a process for confirming whether the player is present at the slot machine 3000 is performed. The confirmation method includes, for example, a method for deciding that a player is present where one or more pieces of credit count data are stored in the storage device 3103. Alternatively, there is a method for deciding that a player is present where one or more pieces of credit count data are stored in the storage device 3103. This confirmation method can be utilized in a game apparatus for storing tokens used by a player as credit data.

It is noted that a method for confirming the player presence is not limited to those described above, and may adopt any other method.

For example, as with the above-described token-operated game machines 1000, 2000, 3000, if a machine is provided with a station control unit 1200, a control unit 2600 of the station unit ST and a main control unit 3100, which are a bet-object receiving unit and a payout processing unit, functioning as bet-object receiving means for receiving bet objects and payout processing means which performs a payout process for paying out to a player an amount of payout objects corresponding to an amount of bet objects received on the basis of the result of game progress controlled by a game progressing unit, the following method may be adopted. That is, receipt timing information for specifying a timing when bet objects (tokens and others) are received by the bet-object receiving unit is detected and stored, then, a determination is made on the basis of the receipt timing information for whether a time elapsed from the latest timing of receiving bet objects to a point in time of being inquired for confirmation of the player presence passes over a predetermined constant time (specified period). Where the time is determined not to pass over, it is highly likely that a player may play a game. Therefore, the result of this determination can be used as useful information for determining that a player plays a game. It is noted that the receipt timing information may include timing indicating data itself (time data) and flag information as with the above-described identification information reading-out timing information.

Further, for example, as with the above-described horse-racing game machine 1000 and the slot machine 3000, if a machine is provided with the RAM 1203 and the storage device 3103 which are a credit data storage unit functioning as credit data storing means for storing credit data as well as the station control unit 1200 and the main control unit 3100 which are a bet-object receiving unit and a credit processing unit functioning as bet-object receiving means for receiving bet objects and credit processing means for performing a credit process in which a part of credit data corresponding to an amount of bet objects received is decreased from credit data stored in the credit data storage unit and also a part of credit data corresponding to an amount of bet objects received by the bet-object receiving unit is increased on the basis of the result of a game, the following method may be adopted. That is, credit change timing information for specifying a timing of change in credit data is detected and stored, and then a determination is made on the basis of the credit change timing information for whether a time elapsed from the latest timing of change in the credit data to a point in time of being inquired for confirmation of the player presence passes over a predetermined constant time (specified period). Where the time is determined not to pass over, it is highly likely that a player may play a game. Therefore, the result of this determination can be used as useful information for determining that the player plays a game. It is noted that the credit change timing information may include data indicating timing itself (time data) and flag information, as with the above-described identification information reading-out timing information.

Further, for example, as with the above-described horse-racing game machine 1000 and the slot machine 3000, if a machine is provided with the touch panel 1012, the start button 3006, the BET operating unit 3015, etc., which are a game operation accepting unit functioning as game operation accepting means for accepting the game operation of a player, thereby controlling game progress according to the operation thereof, the following method may be adopted. That is, game operation timing information for specifying a timing when the game operation has been accepted by the game operation accepting unit is detected and stored, and then a determination is made on the basis of this game operation timing information for whether a time elapsed from the latest timing of accepting the game operation to a point in time of being inquired for confirmation of the player presence passes over a predetermined constant time (specified period). Where the time is determined not to pass over, it is highly likely that a player may play a game. Therefore, the result of this determination can be used as useful information for determining that the player plays a game. It is noted that the game operation timing information may include data indicating timing itself (time data) and flag information as with the above-described identification information reading-out timing information.

Further, as another example, there is a (stock) type of game machine in which a right for activating a slot unit or other miniature drawing apparatus in a pusher game machine and others is obtained by dropping a token into a predetermined winning slot and the right can be retained accumulatively until consumed. In this type of game machine, a player may be determined to play a game in a state where stock remains.

Further, for example, in the above-described token-operated game machines 1000, 2000, 3000, when a player plays a game, a place at which the player is located is substantially fixed. In this type of game apparatus, the following method can be adopted. That is, a presence detecting unit is provided such as an infrared radiation sensor or a touch sensor which detects the player presence at the place. Upon receipt of an inquiry for confirming the player presence, the presence detecting unit determines whether the player is present. Where the presence is detected in this determination, it is highly likely that a player may play a game. Therefore, the determination result that the time is within the period, can be used as useful information for determining that the player plays a game.

The above-described methods for confirming the player presence are able to increase the accuracy of determination effectively by combining these methods with each other to evaluate results determined by each of the methods in a comprehensive manner and determining finally whether the player plays a game. It is noted that the final determination is made in each game apparatus and the result of the final determination may be transmitted to the gaming arcade server 5000. Alternatively, the final determination may be made in the gaming arcade server 5000 or the management server 4000. In the present embodiment 1, an explanation will be made for a case where the final determination is made in each game apparatus and the result of the final determination is transmitted to the gaming arcade server 5000.

Each of the token-operated game machines 1000, 2000, and 3000 performs the player presence confirming process, and then, sends back presence confirming information that is the decision result of that confirming process to the gaming arcade server 5000 from the external communication devices 1108, 2625, and 3107. The control device 5001 of the gaming arcade server 5000 recognizes the station or the station unit or the slot machine played by the player (hereinafter, referred to as a “station and others”) which are specified based on the presence confirming information forwarded from each of the token-operated game machines 1000, 2000, and 3000. Then, the control device 5001 executes a winner determination drawing program so as to perform a winner determination drawing process for determining which drawing target is won while respectively regarding the recognized station and others as the drawing targets. Concretely, a winning table on which each drawing target is assigned an equal winning probability is generated, and a drawing target corresponding to a random number generated based on the winning table is chosen, thereby determining the winning of the chosen drawing target. In the present embodiment 1, in the winner determination drawing process, in addition to the total jackpot award, prepared are: a big winning with a fixed number of pieces of tokens (big bonus award), a medium winning with a fixed number of pieces of tokens (middle bonus award), and a small winning with a fixed number of pieces of tokens (small bonus award). Therefore, for these awards, the control device 5001 sequentially determines the winning drawing target by using the above-described method.

It is noted that the winning probability of each drawing target is set equally; however, it is not always the case. For example, in the gaming arcade server 5000, token consumption data is regularly received from each of the token-operated game machines 1000, 2000, and 3000, and thus, the degree of contribution contributed to an increase in the total accumulated token count data of this time per each of the token-operated game machines 1000, 2000, and 3000 (i.e., a ratio of the token consumption data received from each of the token-operated game machines 1000, 2000, and 3000 for the purpose of increasing the total accumulated token count data of this time) can be specified. For the drawing target corresponding to the token-operated game machine with a high ratio, the winning probability may be relatively increased, and for the drawing target corresponding to the token-operated game machine with a lower ratio, the winning probability may be relatively decreased.

The winner determination drawing process is ended in this way, and the station and others that have won each award are determined. Then, the control device 5001 that is a control command transmitting unit of the gaming arcade server 5000 functions as control command transmitting means, informs each of the token-operated game machines 1000, 2000, and 3000 of the winning result, and at the same time, transmits the total performance control command to each of the token-operated game machines 1000, 2000, and 3000.

Thereby, the total jackpot performance that utilizes the performance unit of each of the token-operated game machines 1000, 2000, and 3000 connected to the gaming arcade server 5000 is carried out.

Next, the total jackpot performance will be explained.

In each of the token-operated game machines 1000, 2000, and 3000 that has received the total performance control command from the gaming arcade server 5000, jackpot start screens to the effect that a total jackpot drawing is started as shown in FIG. 16 are simultaneously displayed on the display 1011, the display unit 2700, and the performance panel 3011 that are display units of the station and others relating to the drawing target. At the station and others that are not the drawing targets, i.e., the station and others at which it is decided that a player is not playing the game, this jackpot start screen is not displayed.

In the present embodiment 1, at the station and others that are not drawing targets, a player is capable of playing a game of the token-operated game machine even during the total jackpot performance. Thus, there is a probability that during the total jackpot performance, an individual performance according to the game progress at the station and others that are not the drawing target is carried out. However, it is probable that if an individual performance not related to the total jackpot performance is carried out during the total jackpot performance, the total jackpot performance is impeded by the individual performance, thereby decreasing a good characteristic of the total jackpot performance. Therefore, in the present embodiment 1, the station and others that are not the drawing targets are controlled so that the individual performance according to the game progress is not carried out or a subtle performance only is carried out by decreasing a sound volume, a light amount, etc., so that the individual performance does not stand out during the total jackpot performance.

As a result of working solely or working together with the other control devices 1201, 2601, and 2611, the control devices 1101, 2621, and 3101 that are advance notification performance control units of the respective token-operated game machines 1000, 2000, and 3000 function as advance notification performance control means so as to carry out the total jackpot performance process by executing the total performance program. In particular, when the performance units such as the speaker and the illuminating device of each of the token-operated game machines 1000, 2000, and 3000 are caused to carry out a performance assuming part of the total jackpot performance, it becomes possible to carry out a single total performance (total jackpot performance) in which all the token-operated game machines 1000, 2000, and 3000 connected to the gaming arcade server 5000 are cooperated with each other. Concretely, for example, in all the token-operated game machines 1000, 2000, and 3000, illumination in blue and red are alternately emitted at the same timing, the same music or sound effect to the effect that either player who plays by using these token-operated game machines has won the total jackpot award is output at the same timing, and other similar effects are provided.

It is noted that, in the present embodiment 1, the performance unit of each of the token-operated game machines 1000, 2000, and 3000 is configured by hardware different from each another, and thus, it is not possible to carry out the completely same performance. To solve this, it may be possible to carry out the total jackpot performance that gives a sense of unity as a whole by deliberately combining the performances different from each other at each of the token-operated game machines 1000, 2000, and 3000. As an example of music and sound effect, the horse-racing game machine 1000 may take a low-sound part, the pusher game machine 2000 may take a middle-sound part, and the slot machine 3000 may take a high-sound part.

There are specific, various performance methods for the total jackpot performance that can carry out a performance that gives a sense of unity as a whole, which is achieved as a result of a mutual synchronization of the performances provided by the performance units of each of the token-operated game machines 1000, 2000, and 3000.

By starting the total jackpot performance in this way, the players and audience in the gaming arcade can know that someone of the players playing the token-operated game machines in the gaming arcade wins the total jackpot award within. Thus, the player develops a sense of expectancy to the effect that the player him/herself may win the jackpot award and waits a notification of the drawing result.

After the total jackpot performance is started in this way, on each of the display units 1011, 2700, and 3011, a slot screen as shown in FIG. 17 is displayed subsequent to the jackpot start screen as shown in FIG. 16. Then, after the three reel images on the slot screen start a varying display, stop/display control is performed on the three reel images on each of the display units 1011, 2700, and 3011 so that symbols that reflect winning or losing at the respective corresponding station and others are stopped and displayed. Concretely, in the present embodiment 1, as described above, there are the four awards, i.e., the total jackpot award, the big bonus award as a payout award, the middle bonus award as a payout award, and the small bonus award, as a payout award and the stop/display control is performed so that a combination of symbols corresponding to the respective awards is stopped and displayed on the slot screen. More particularly, on the display units 1011, 2700, and 3011 of the station and others that have won the total jackpot award, the stop/display control is performed so that three identical A symbols are stopped and displayed. On the display units 1011, 2700, and 3011 of the station and others that have won the big bonus award, the stop/display control is performed so that three identical B symbols are stopped and displayed. On the display units 1011, 2700, and 3011 of the station and others that have won the middle bonus award, the stop/display control is performed so that a combination of symbols mixed with the A symbols and B symbols is stopped and displayed. On the display units 1011, 2700, and 3011 of the station and others that have won the small bonus award, the stop/display control is performed so that a combination of symbols is stopped and displayed. In this case, the combination is: the A symbol or the B symbol is stopped and displayed on both a left reel image and a middle reel image, and neither the A symbol nor the B symbol is stopped and displayed on a right reel image (i.e., a blank symbol is stopped and displayed).

It is noted that there is no need that the jackpot start screen and the slot screen are completely the same in all the token-operated game machines 1000, 2000, and 3000. For example, these screens may be appropriately modified according to hardware with which these screens are displayed, or may be arranged according to the game content of each of the token-operated game machines 1000, 2000, and 3000.

Moreover, in the present embodiment 1, the varying display of the reel images on the slot screen is simultaneously started in all the token-operated game machines 1000, 2000, and 3000 connected to the gaming arcade server 5000; however, a completion timing at which the three reel images are stopped and displayed is differed depending on each award. Concretely, with respect to a time it takes for the stop display completion timing, it takes the least time for the station and others corresponding to the loss; it gradually takes more time in the order of the small bonus award, the middle bonus award, the big bonus award, and the total jackpot award.

Further, in the present embodiment 1, also while the varying display of the reel images on the slot screen is started and the stop display is completed, the total jackpot performance (advance notification performance) is continued. For example, after the varying display of the reel image is started on the slot screen, the performance is carried out so that the station and others illuminated with a light are sequentially switched. In this case, the illumination of the corresponding station and others (that are drawing targets of each of the token-operated game machines 1000, 2000, and 3000) are lit only in periods different from each other. Then, the drawing performance is carried out so that at the timing at which the stop display of the reel images at the station and others is completed, the illumination of the station and others is flashed.

After the total jackpot performance is ended in this way, a process for paying out tokens of which the number of pieces corresponds to that of each award is performed for the player who plays at the station and others that have won each award. This token payout may be performed by utilizing the token payout unit of the token-operated game machines 1000, 2000, and 3000, or may be performed by way of an attendant pay in which the payout is made by an employee at the gaming arcade.

In the present embodiment 1, the total accumulated token count data indicates a value obtained by adding the number of tokens to be paid out to the player who has won the total jackpot award and the number of tokens to be paid out to the player who has won the payout award (the big bonus award, the middle bonus award, and the small bonus award). That is, when winning of the total jackpot award is determined, a predetermined number of tokens that is a part of the total accumulated token count data is paid out to the player who has won the payout award, and the remaining number of tokens is paid out to the player who has won the total jackpot award. In this case, the total accumulated token count individually displayed in each token-operated game machine may not display the number of tokens indicated by the total accumulated token count data but display only a part thereof, i.e., the number of tokens to be paid out when the total jackpot award is won.

It is noted that the total accumulated token count data indicates only the number of tokens to be paid out to the player who has won the total jackpot award, and the number of tokens for the payout award (the big bonus award, the middle bonus award, and the small bonus award) may be stored as data different from the total accumulated token count data.

As described so far, according to the present embodiment 1, a total jackpot drawing can be performed by giving a drawing target only a game apparatus highly likely to be played by a player among all the game apparatuses capable of participating in the total jackpot drawing. Thereby, since there is less likelihood of a situation where the jackpot award is won in a game apparatus which is not played by the player, a jackpot drawing start condition can be used a condition which is not related to a game play of the player playing a game with each game apparatus. Therefore, it is possible to increase the degree of freedom of the jackpot drawing start condition.

Further, there is less likelihood of a situation where the jackpot award is won in a game apparatus which is not played by a player. The above-described total jackpot performance is made possible in which the jackpot award is won from a plurality of game apparatuses. Thus, conventional disadvantages can also be improved.

Embodiment 2

Hereinafter, an explanation will be made for the present invention by referring to one embodiment (hereinafter, the present embodiment is referred to as a “embodiment 2”) which is applied to a game system constituted with three types of token-operated game machines, that is, arcade game machines (game machines for business use), the game content of which is different from each other as well as a gaming arcade server and a management server as a jackpot drawing apparatus connected in a manner to enable communication with these machines, as with the above-described embodiment 1.

The present embodiment 2 is similar to the above embodiment 1 in a basic constitution but greatly different in that a jackpot drawing process is performed at the gaming arcade server 5000 and the jackpot drawing process is performed individually at each of the token-operated game machines 1000, 2000, 3000 and also different in a manner of performing a jackpot drawing or others. These differences from embodiment 1 will be explained hereinafter.

It is noted that among various modified examples explained in the above-described embodiment 1, modified examples similarly applicable to the present embodiment 2 may be changed in content.

FIG. 18 is a sequence flowchart showing a flow of a total jackpot drawing in the present embodiment 2. In FIG. 18, for the sake of explanation, only one token-operated game machine and one gaming arcade server are shown.

In the present game system, when a player consumes tokens at each of the token-operated game machines 1000, 2000, 3000, data indicating the tokens consumed is transmitted to the gaming arcade server 5000 in the gaming arcade thereof, together with a game machine ID as game apparatus identification information for identifying a game apparatus which is played by the player (the station 1010 of the horse-racing game machine 1000, the station unit ST of the pusher game machine 2000 or the slot machine 3000). It is noted that if the function to manage the player identification information as found in the above-described horse-racing game machine 1000 is provided in each game apparatus, the player identification information may be used in place of the game machine ID.

As with the above-described embodiment 1, the control device 5001 of the gaming arcade server 5000 stores accumulatively in the storage device 5002 a part of tokens consumed by each player (for example, 0.01 pieces) as intra-arcade accumulated token count data on the basis of token consumption data transmitted from each of the token-operated game machines 1000, 2000, 3000. As with the above-described embodiment 1, the control device 5001 transmits the intra-arcade accumulated token count data within the storage device 5002 to the management server 4000 at a predetermined timing. Then, as with the above-described embodiment 1, the management server 4000 accumulatively adds a part of the number of tokens indicated by the data to total accumulated token count data within the storage device 4002 when receiving the intra-arcade accumulated token count data transmitted from each gaming arcade server 5000.

In the total jackpot drawing of the present embodiment 2, a process in which when any one of the game apparatus 1010, ST, 3000 satisfies a predetermined drawing start condition, a determination is made for whether the total jackpot award is won in a game apparatus which has satisfied the drawing start condition, is performed. Here, in the present embodiment 2, a total jackpot drawing start condition is to bet a predetermined number of tokens (for example, 100 pieces). In addition to this, any other publicly known drawing start condition may be adopted. More specifically, for example, that a bet operation is performed, that a token drop-in sensor detects a token dropped in, that a signal for commencing the change in symbol display on a slot machine is turned ON and that the number of tokens paid out is in excess of a predetermined number (10 pieces), are included. Further, the total jackpot drawing start condition and winning probability of a total jackpot award may be made different among game apparatuses constituting the present game system. Where the total jackpot drawing start condition is made different among game apparatuses, it is desirable that the drawing start condition is set to be the same in game apparatuses of the same type. Where winning probability of a total jackpot award is made different among game apparatuses, the winning probability in each of the game apparatuses may be made different according to a drawing start condition set in the game apparatus concerned.

In the present embodiment 2, upon receipt of token consumption data and the game machine ID from each of the game apparatus 1010, ST, 3000, the control device 5001 of the gaming arcade server 5000 adds accumulatively a part of the number of tokens indicated by the token consumption data to individual count data within the storage device 5002 in association with the game machine ID concerned. Then, where the number of tokens indicated by the individual count data is in excess of 100 pieces, the control device 5001 performs a process for decreasing the number of tokens corresponding to 100 pieces from the individual count data, thereby executing a total jackpot drawing program to perform the total jackpot drawing. In this total jackpot drawing, a determination is made for whether the total jackpot award is won by checking a generated random number in reference to the predetermined winning table.

In the present embodiment 2, an explanation has been made by exemplifying a case where, as with the gaming arcade drawing of the above-described embodiment 1, the total jackpot drawing is performed individually in the game apparatus 1010, ST, 3000 which satisfies a condition for starting a predetermined jackpot drawing. As with the winner determination drawing process explained in the above-described embodiment 1, the same is applicable to a case where a game apparatus which wins the total jackpot award is determined by a single drawing from a plurality of apparatuses, that is, the game apparatuses 1010, ST, 3000. However, where the total jackpot drawing is performed individually in the game apparatuses 1010, ST, 3000 as in the present embodiment 2, it is not necessary to adjust a timing for performing the total jackpot drawing among a plurality of apparatuses, that is, the game apparatuses 1010, ST, 3000. This is advantageous in simplifying the total jackpot drawing process.

In the total jackpot drawing of the present embodiment 2, when winning is determined in any one of the game apparatuses 1010, ST, 3000, first, a gaming arcade drawing performance is carried out as if a gaming arcade drawing were performed for determining a gaming arcade which wins the total jackpot award from a plurality of gaming arcades. In the present embodiment 2, since a winner of the total jackpot award has already been determined, in this gaming arcade drawing performance, a drawing process is not performed but only a performance is carried out as if just a drawing were performed. In other words, this gaming arcade drawing performance may be a performance that notifies which gaming arcade has a winner of the total jackpot award.

In the gaming arcade drawing performance of the present embodiment 2, when winning is determined in any one of the game apparatuses 1010, ST, 3000, first, the control device 5001 of the gaming arcade server 5000 transmits winning data showing to the effect that an award has been won to the management server 4000, together with a game machine ID of any winning one of the game apparatuses 1010, ST, 3000. The control device 4001 of the management server 4000 which has received the winning data performs a gaming arcade selecting process for selecting a gaming arcade which carries out the gaming arcade drawing performance. It is not necessary to perform the gaming arcade selecting process where the gaming arcade drawing performance is carried out in all gaming arcades provided with the gaming arcade server 5000 which constitutes the present game system. However, where the gaming arcade selecting performance is carried out in all the gaming arcades, the number of apparent drawing targets (the number of gaming arcades) is increased. As a result, there is greater likelihood of a situation where the gaming arcade drawing performance has been carried out but no award is won in any of the game apparatuses within a gaming arcade. Players at each gaming arcade realize a lower winning probability (apparent winning probability) of their gaming arcade and hardly have a winning expectation. Consequently, the gaming arcade drawing performance may fail in livening up the winning Therefore, in the present embodiment 2, the gaming arcade selecting process is performed so that the gaming arcade drawing performance is to be carried out not in all gaming arcades but in a limited number of gaming arcades. Thereby, the players are allowed to realize a higher apparent winning probability that an award may be won in their gaming arcade, having a greater expectation so that the gaming arcade drawing performance can liven up the winning It is noted that a gaming arcade selecting condition and the number of gaming arcades to be selected in the gaming arcade selecting process may be set appropriately. However, it is necessary to select a gaming arcade having a winner of the total jackpot award without fail.

The control device 4001 of the management server 4000 selects a gaming arcade for carrying out a gaming arcade drawing performance by the gaming arcade selecting process and thereafter issues a gaming arcade performance command to the gaming arcade server 5000 of the selected gaming arcade. Then, in the gaming arcade server 5000 which receives the gaming arcade performance command, the gaming arcade drawing performance process is performed. The gaming arcade drawing performance process displays a gaming arcade drawing slot screen as shown in FIG. 19 on a large-size display (not shown) connected to the gaming arcade server 5000. Below the gaming arcade drawing slot screen, the number of tokens paid out when the total jackpot award is won this time (the number of total accumulated tokens) is displayed. Further, on the gaming arcade drawing slot screen, an image that frames displaying respectively the name and area of a gaming arcade selected by the gaming arcade selecting process moves on the screen from above to below in a predetermined order is displayed. Then, finally, as shown in FIG. 20, a frame of the gaming arcade having a winner of the total jackpot award (gaming arcade A) is stopped and displayed. Thereby, a player who looks at the large-size display of the gaming arcade where the gaming arcade drawing performance has been carried out is able to realize that a winner of the total jackpot award is determined among players who play at the gaming arcade A. As a result, a player who plays at the gaming arcade A will have a greater expectation that the player may win the award.

Here, as the gaming arcade drawing performance process, an explanation has been made for a process for displaying the gaming arcade drawing slot screen on the large-size display connected to the gaming arcade server 5000. However, other process methods may be adopted. These methods include a process method for displaying the above-described gaming arcade drawing slot screen by utilizing a display unit of each of the token-operated game machines 1000, 2000, 3000 and a process method for carrying out a gaming arcade drawing performance by vocal announcement.

After the gaming arcade drawing performance is ended as described above, the gaming arcade server 5000 of the gaming arcade having a winner of the total jackpot award (gaming arcade A) performs the total jackpot performance process as if a winner determination drawing were performed for determining a winner of the total jackpot award among players who play at the token-operated game machines 1000, 2000, 3000 within a gaming arcade connected thereto. In the present embodiment 2, since the winner of the total jackpot award has already been determined, in the total jackpot performance process, a drawing process is not performed but only a performance is carried out as if just a drawing were performed. In other words, a performance by the total jackpot performance process may be a performance that notifies which player has won the total jackpot award. As with the above-described embodiment 1, the total jackpot performance process of the present embodiment 2 gives a player a sense of expectation that the player may be a winner or arouses an interest that someone may be a winner. Therefore, this process is expected to attract attention from players, an audience and others in a gaming arcade as a whole.

The total jackpot performance also needs to be carried out simultaneously at all the token-operated game machines 1000, 2000, 3000 within a gaming arcade. Therefore, as with the above-described embodiment 1, a process for determining a total jackpot performance period is performed. Then, upon arrival of the total performance period, as shown in FIG. 18, the control device 5001 of the gaming arcade server 5000 performs a winning player presence confirming process for confirming the presence of a player in any one of the game apparatuses 1010, ST, 3000 which has won the jackpot award this time. The winning player presence confirming process is similar to the player presence confirming process in the above-described embodiment 1 excluding a point in which only a winning one of the game apparatuses 1010, ST, 3000 is regard as an object.

In the player presence confirming process of the above-described embodiment 1, confirmation is made not only for whether a player is present but also for whether the player actually plays a game. However, in the present embodiment 2, it is not necessary to confirm whether a player actually plays a game. This is because the winning player presence confirming process of the present embodiment 2 will be sufficient only if a winning player is confirmed not to leave a game apparatus yet. Therefore, for example, in the horse-racing game machine 1000, a confirmation will be sufficient that the magnetic card is inserted into the magnetic-card inserting slot 1015, or an ID code which is player identification information read out from the magnetic card is stored in the RAM 1203 which is an individual information storage unit functioning as individual information storage means, or credit data is stored in the RAM 1203. More specifically, only a confirmation will be sufficient that credit data corresponding to one or more pieces of tokens are stored in the RAM 1203.

More specifically, in the horse-racing game machine 1000, where confirmation is made for whether an ID code read from the magnetic card is stored in the RAM 1203 to perform the winning player presence confirming process, the station control device 1201 which is a decision information detecting unit of the station 1010, that is, a winning game apparatus, is inquired for confirmation of the player presence, thus functioning as decision information detecting means. Thereby, the station control device 1201 confirms whether the ID code is stored in the RAM 1203 and transmits to the gaming arcade server 5000 the confirmation result as individual-information-presence-information which is decision information. Then, the control device 5001, that is, a player presence decision unit of the gaming arcade server 5000, functions as player presence determining means. After receipt of individual-information-presence-information to the effect that the ID code is stored, the control device 5001 determines that the ID code is stored in the RAM 1203 of the station 1010 and determines that a player is present at the station 1010.

Further, in the horse-racing game machine 1000, where the storage of credit data in the RAM 1203 is confirmed to perform the winning player presence confirming process, the station control device 1201 which is a decision information detecting unit of the station 1010, that is, a winning game apparatus, functions as decision information detecting means by being inquired for confirmation of the player presence. Further, the station control device 1201 confirms whether the credit data is stored in the RAM 1203, thereby transmitting to the gaming arcade server 5000 the confirmation result as credit presence information which is decision information. Then, the control device 5001 which is a player presence decision unit of the gaming arcade server 5000 functions as player presence determining means. Upon receipt of the credit presence information to the effect that the credit data is stored, the control device 5001 determines that the credit data is stored in the RAM 1203 of the station 1010 and also determines that a player is present at the station 1010.

The method for confirming the presence of a winning player is able to increase the accuracy of determination effectively by combining methods explained in the present embodiment 2 and those explained in the above-described embodiment 1 with each other to evaluate results determined by each of the methods in a comprehensive manner, thereby finally determining the player presence.

The winning player presence confirming process is ended, as described above, to confirm the player presence in any one of the game apparatuses 1010, ST, 3000 which has won the jackpot award this time. Then, the control device 5001 of the gaming arcade server 5000 notifies each of the token-operated game machines 1000, 2000, 3000 of the winning result of the jackpot drawing and also transmits a total performance control command to each of the token-operated game machines 1000, 2000, 3000. Thereby, the performance unit of each of the token-operated game machines 1000, 2000, 3000 connected to the present gaming arcade server 5000 is utilized to carry out the total jackpot performance.

On the other hand, where player presence is not confirmed in any one of the game apparatuses 1010, ST, 3000 which has won the jackpot award this time, in the present embodiment 2, an alternative winning determination process is performed in the gaming arcade server 5000. The alternative winning determination process is a process in which in place of any one of the game apparatuses 1010, ST, 3000 which has won an award but from which a player has left, the jackpot award is to be won in another one of game apparatuses 1010, ST, 3000. The alternative winning determination process of the present embodiment 2 determines the winning of the total jackpot award in another one of the game apparatuses 1010, ST, 3000 by a drawing process which uses accumulated token consumption data stored within the storage device 5002 of the gaming arcade server 5000.

More specifically, upon receipt of token consumption data and a game machine ID from each of the game apparatuses 1010, ST, 3000, the control device 5001 of the gaming arcade server 5000 accumulatively adds the number of tokens indicated by token consumption data not only to individual count data within the storage device 5002 but also to accumulated token consumption data within the storage device 5002 in association with the game machine ID. The accumulated token consumption data is an accumulated value for each game machine ID of token count indicated by the token consumption data received within a predetermined period (for example, the latest 30 minutes). In the present embodiment 2, the game apparatuses 1010, ST, 3000 storing the game machine ID within the storage device 5002 are regard as drawing targets excluding such game apparatuses 1010, ST, 3000 that have won the jackpot award but from which a player has left. And a random number drawing which is set so as to increase a winning probability in a game apparatus having a greater number of tokens indicated by the accumulated token consumption data is performed. A game apparatus which has won an award by this drawing is confirmed by a process similar to the above-described winning player presence confirmation process for whether a player is present. Then, upon confirmation of the player presence, the control device 5001 of the gaming arcade server 5000 notifies each of the token-operated game machines 1000, 2000, 3000 of the winning result and also transmits the total performance control command to each of the token-operated game machines 1000, 2000, 3000. Thereby, the performance unit of each of the token-operated game machines 1000, 2000, 3000 connected to the present gaming arcade server 5000 is utilized to carry out the total jackpot performance.

The content of the total jackpot performance may be similar to that of embodiment 1. However, in the present embodiment 2, only the winning of the total jackpot award is determined. Therefore, on the slot screen of the display unit 1011, 2700 or 3011 of any winning one of the game apparatuses 1010, ST, 3000, stop/display control is provided so that a combination of symbols corresponding to the total jackpot award is stopped and displayed. On the slot screen of the display unit of other game apparatuses which fail in winning an award, stop/display control is provided so that a combination of symbols corresponding to loss is stopped and displayed. As with the above-described embodiment 1, where payout awards such as the big bonus award, the middle bonus award and the small bonus award are subjected to a drawing process in advance, stop display and control may be provided so that combinations of symbols corresponding to the awards are stopped and displayed on the slot screens of the display units 1011, 2700 and 3011 of the game apparatuses 1010, ST, 3000 which have won these awards.

After the total jackpot performance is ended as described above, a token payout process is given to a player playing with any one of the game apparatuses 1010, ST, 3000 which has won the total jackpot award according to the number of tokens corresponding to the award. These tokens may be paid out by utilizing token payout units of the token-operated game machines 1000, 2000, 3000 or may be paid out in terms of attendant pay in which the tokens are paid out by an employee of a gaming arcade.

As described so far, according to the present embodiment 2, at a predetermined timing at which after the winning of the total jackpot award is determined but before the total jackpot performance process is performed, confirmation is made for the presence of a player in any one of winning game apparatuses 1010, ST, 3000. Then, when the player is not present at the game apparatus concerned, the token payout process is not performed for the total jackpot award in the game apparatus concerned. Therefore, even where before the player who has won the jackpot award is aware of the winning, the player leaves the game apparatus, it is possible to avoid a situation where the total jackpot award is paid out to the player. In particular, in the present embodiment 2, the winning player is able to be aware that the player has won the jackpot award at a time when a gaming arcade drawing performance is ended after the winning of the total jackpot award is determined and the total jackpot performance process which is performed after arrival of the total jackpot performance period is also ended. Thus, there can be present a player who plays with any one of the game apparatuses 1010, ST, 3000 at the time of winning but finishes play with any one of the game apparatuses 1010, ST, 3000, for example, in the middle of the gaming arcade drawing performance. According to the present embodiment 2, the above situation will not take place despite the presence of the player. Therefore, there is no case where the total jackpot drawing performance and various conditions such as the jackpot drawing start condition are limited to an extent so as to prevent the above situation. Thus, the degree of freedom is greatly increased in various conditions.

It is noted that, instead of being applied to the above-described types of machines, the token-operated game machine applicable to the game system of the present embodiment 1 and embodiment 2 can be applied to a wide use.

Also, the gaming arcade server 5000 of the present embodiment 1 and embodiment 2, which is a apparatus dedicated to the present game system to which only the token-operated game machines 1000, 2000, and 3000 participating in the total jackpot drawing are connected, may be a general gaming arcade server to which also the other token-operated game machines not participating in the total jackpot drawing are connected.

Methods for confirming the player presence explained in the present embodiment 1 and embodiment 2 shall not be limited to specification of drawing targets in the jackpot drawing but may be widely applicable to a decision for whether a player plays with the game apparatus concerned or not.

In the above-described embodiment 1 and embodiment 2, means realized by software such as a computer program may be optionally realized by hardware such as a circuit board and a chip. Moreover, means realized by hardware such as a circuit board and a chip may be optionally realized by software such as a computer program.
